How quickly does nitazoxanide work?

Nitazoxanide 200 mg is an antiparasitic and antiviral medication that typically begins to work within 24 to 48 hours. It is commonly used to treat infections caused by protozoa and helminths, such as giardiasis and cryptosporidiosis. The exact time frame for its effectiveness can vary depending on the type and severity of the infection being treated. Patients usually experience a significant reduction in symptoms within a few days of starting the medication. However, it is crucial to complete the full course prescribed by a healthcare provider to ensure the infection is fully eradicated.
